Effects of Nitrogen Additions on Soil Carbon Pools in Two Humid Tropical Forest Types

Lead Institution

Colorado State University

Principal Investigator

Daniela Cusack

Project type

Large-Scale EMSL Research

Human activity has greatly increased available nitrogen (N) on Earth, with N deposition rates in tropical regions predicted to be the highest globally in coming decades. Because plant growth is not…

VEGETATION INFLUENCES ON LONG-TERM CARBON STABILIZATION IN SOILS, VIA PLANT ALLOCATION, TISSUE CHEMISTRY,
AND SOIL DEPTH EFFECTS

Lead Institution

Lawrence Berkeley National Laboratory

Principal Investigator

Margaret Torn

Project type

Exploratory Research

Soil organic matter is a major reservoir of carbon within the biosphere and has a fundamental impact on soil properties, and therefore on ecosystem functioning and sustainability. We are proposing to…

Vegetation Influences on Long-Term Carbon Stabilization in Soils: A Continuation of Previous Research

Lead Institution

Lawrence Berkeley National Laboratory

Principal Investigator

Margaret Torn

Project type

Large-Scale EMSL Research

This project is a continuation of our previous research that investigates the influence of vegetation on long-term carbon stabilization in soils using molecular level analysis. Previously, we have…

Soil Carbon Stabilization At The Permafrost-Active Layer Boundary In An Arctic Tundra Ecosystem

Lead Institution

Lawrence Berkeley National Laboratory

Principal Investigator

Margaret Torn

Project type

Large-Scale EMSL Research

In preliminary studies, we have observed a stock of old, seemingly stable carbon immediately above the permafrost in soils from Barrow, Alaska. The proposed study will focus on the mechanisms…

Beyond the rhizosphere: Microbial functional traits through the whole soil profile and their response to warming.

Principal Investigator

Eoin Brodie

Project type

FICUS Research

The pathways of carbon transport and loss through and from soils--soil organic matter (SOM) depolymerization to dissolved organic carbon and mineralization to carbon dioxide (CO2)--are fundamentally…

Stablilization of soil organic matter: land use, erosion and burial

Lead Institution

Lawrence Berkeley National Laboratory

Principal Investigator

Margaret Torn

Project type

Capability Research

We are proposing to use 13C-NMR spectroscopy to analyze the relative abundance of organic functional groups in soil organic matter (SOM) to better understand the mechanisms of carbon (C) cycling and…
